To all whom t may concern.'

Beit known that'I, MARY CHASE BARON, a citizen of the United States, residing at Hampden Meadows, in the State of Rhode Island, have inventedy certain new and useful Improvements in Brooders, of which' the following is a specification, reference being had therein to. the accompanying drawing.

This invention relates to certain new and useful improvements in brooders ofthe hot water heated type, and has for its object to improve the hot `water heating', system and the control ofthev same whereby a uniform temperature may be maintained throughout the brooding chamber.

'The invention further consists in setting the hot water tank in substantially a horizontal plane and spacing the top and bottom walls but a short distance apart to accommodate comparatively thin vvolume of water of extended area, the tank alsohavinga heatdeflecting hood spaced jusjt'above it and so shaped as to deiiect the heat from the tank downward inthe brooding space upon the backs of the chicks below. 1

A still further object of the f invention is to place the heat generator outside of the brooding space and provide an air space and a separating wall between the generatoryspacebecomes hotter than another, particul and theibrooding chamber to reventthat` portion o f the chamber nearest t e generator from becomlng overheated, as

` hen any, one'l larly in cold weather, the-chicks crowd to that place and many become jammed and smothered...

Thefinvention ,furtherr'esides in an .improved forln of hot water ltank or boilerihaving an extensionoverlying a. source of heat and embodying a fine passn source :is conducted.

he invention has for another aiinuto pro vide independent regulators controllable by,

thermostatic [devices within the brooding s ace or controlling the escape of: heat from tlie brooding space and also for regulating 1the current of heat .through .the flue of the boiler. l

Application for -ments and combinations hereinafter dethe same with hot water instead of hot air for several reasons; first, hot air heat dries the moisture from the hovering space, particularly during cold weather when an intense heat is required, to such an extent that the chicks have a tendency to contract a distemper causing running at the nose, similar to a cold, preventing them Ifrom thriving, which effect is quite absent where hot-water heat is employed: second, hot-air heat cannot be kept `uniformin temperature 4whereas the temperature from hot` water heating changes comparatively slowly, thus when oil burnlngheaters are employed the. heat diminishes as the oil becomes low, which elect israt once noticeable'in a brooder where hot air onlyis employed; third, by hot air the brooder can'be more readily overheated and kill'ithe chicks', even with a moderately low i'am'e in the heater, but the characteristic evennessof hot water heat is generally known. these `dificulties are eil'ectually obviated by the use offmyimproved water tank as the water therein will main-v spaced a short'distance 'apart to inclose a com- -of the surrounding air in the paratively thin body of water of extended area so as to radiate the maximum amount of heat, and still be of sufficient volume to hold the heat and maintain a uniform Vtem.- perature which is 0f utmost importance. This tank is supported above the flooringv 2 of the brooding space or brooder by legs 3 and placed just the proper distance above the backs ofthe chicks to keep their vitals warm the same as when under the wings of the mother hen and a sheet metal hood 5 is supported a short distance above this tank by shortlegs 4 to prevent the escape of the rising heat.-

This hood is also preferably constructed of metal and preferably provided with a flaring outer edge by which the direct heat from the tank which is collected beneath it, is deflected downwardly into the brooding space below. Then again by forming this hood of uncovered or noninsulated metal some heat is permitted to radiate from its heated outer surface to` raise the temperature p room in which the broeder is located thereby tempering the adjacent interior of the room, so `that when the little chicks run' out from under the brooder hood as they would from under the wings of the mother hen, they will not become unduly chilled.

To one side of the hood 5 is a lamp chamber 8 being accessible through door' 9' and containing a suitable support 10 for a heating lamp 11, preferably of the blue-flame type. The boiler has a lateral extension 12 overlying 'the lamp chimney 13 and opening directly .over the latter is the wide mouth 14 of a heating iiue 15. This flue is in the form of a flattened rectangular sectioned pipe disposed Awithin the boiler and leading from the lateral boiler extension 12 through the boiler in a somewhat arcuate course .and opening upwardly through the top of the boiler, at a substantially diametrically opposite point, into the lower end of an escape flue or chimney 16 which is superposed upon the hood. A damper plate 17 is adapted for setting on and closing the discharge end 18 of the heat- ,ing due 15, said plate being carried by one end of a lever 19 fulcrumed in a hood-supported bracket 20 and controlled by means of a thermostat 21 arranged within the brooding chamber and suitably supported by the bracket 22. When the damper plate is seated on the flue extension or end 18 the gases and odors backing up into and accumulating in the lamp chamber are conducted therefrom through a bypass ventilating pipe 23 that provides a shunt or direct passage from the lamp chamber to the chimney 16. A valve controlled air inlet 24 is provided Ain the lamp chamber to promote combustion, as is obvious.

A Ventilating flue or pipe 25 passes upwardly through the boiler and top of the hood, and this ventilating u'e is controlled by means of a damper plate 26 operating over the upper end thereof, said plate being likewise supported on one end of a weighted lever 27 that is pivoted in bracket 28, on the hood, and controlled by the thermostat 29 arranged Within the brooding space on the bracket 30. An expansion tank 31 is mounted above the boiler and connected therewith, and an air' vent pipe 32 rises from the boiler at one side through which the boiler may be filled, an outlet 34, in its bottom, providin a drain therefor. TheV hood is lined Witli asbestos sheeting 33 to limit heat radiation throughv its walls.

It is also found to be of importance-to provide an air space 35 and'y a wall 36 be` tween the lamp chimney 13 and the brooding space 7 so as toefectually prevent that part of the brooder adjacent the lamp from becoming overheated, as in severe weather if any particular zone becomes warmer than another'the chicks will crowd in that direction with 'the result that many become smothered and crushed and it is for' thisl reason that I have placed vthe heat generator outside of the brooding'charn'ber proper and positioned this wall between'the brooding space and the generator, it being found in practice that the temperature of the entire brooding chamber nearly uniform as possible in order 'to ob-v tain the best results.

In operation, the burner or heater 11 is ignited to discharge its products of combustion in the inlet end of the boilercontained flue, the opposite end being closed'by 'the damper' plate' 17. vThe odors from the lamp are permitted to escape through the by-pass iiue so that free from poisonous gases. In' addition to' the heat entering the boiler flue, it will also act on the boiler extension to further heat the water' in the boiler in an expeditious manner. c

As the temperature inthe brooding space rises the thermostat 29 is designed to operate first in lifting yits damper plate off from the Ventilating pipe 2 5. 1f the temperature then continues to rise the thermostat 21 will operate to lift the damper plate 17 from oif the boiler flue so that the products of combustion will readily pass from the flue to the chimney 16. v

The arcuate or circular configuration of the fiattened Hue affords increased heating area and also permits the Ventilating pipe 25 to be disposed centrally of the hood. The ends of the heating flue are welded to make a tight joint with the boiler. The shallow hat circular boiler is quickly heated and forms a roof for the entire brooding chamber. By reason of the extended boiler portion and the flattened heating flue therein, but a small film of Water is brought in should be maintained as" the chick .compartment will be contact With the flue and all the heat generated inthe lamp or heater chamber will act o n the said boiler extension so that after the IWater is once heated there will be no trouble in maintaining a uniform heat in the broeder.
